The announcement came in a blog post by Rackspace Product and Engineering Senior Vice President Mark Interrante, where he explained how "workloads that run well on Cloud Servers today will run even better on Performance Cloud Servers."

"These servers have been engineered to deliver exceptional levels of application performance, with greater speed, throughput, reliability and scale," he said.

Interrante said these servers were built with the following:

100 percent data center-grade solid-state disks (SSDs).

Intel Xeon E5 processors, as much as 120 GB of memory and 40 gigabits per second of available network throughout to every host.

A powerful hosting platform for a wide variety of workloads, ranging from basic web servers to large scale NoSQL data stores such as MongoDB and Cassandra.

"The performance gains enabled by this new product extend beyond the servers themselves," Interrante said, noting a boost in Cloud Block Storage performance, as well as improved performance on Cloud Databases, Cloud Load Balancers, Cloud Files and more.

Performance Cloud Servers are now available in Rackspace's Northern Virginia region, moving to Dallas, Chicago, and London regions later in November. Sydney and Hong Kong regions will follow in the first half of 2014.

"If you liked Cloud Servers, you’re going to love Performance Cloud Servers," he said. "If you’ve never tried Cloud Servers, now is the time. We are leveraging the power of OpenStack, the world’s leading open source cloud operating system, to deliver extreme server performance on demand."
